The AZURA® Pilot LC 100 System offers the best conditions for transferring separations from the analytical to the preparative scale. Whether simple analyzes or demanding purification, the Pilot LC 100 system has combined the best solution in one system for a wide range of requirements.

System components

The system consists of a pump (AZURA® P 2.1L) with 100 ml pumphead and with a maximum flow rate of 100 ml/min. Within this flowrate range you can purify very large sample sizes up to 70 g per day. The injection is carried out via the automatic injection valve installed in the assistant. Thanks to the KNAUER VariLoop, up to 40 ml sample solution can be injected at once or step by step without any dilution. The system is completed by a UV-detector and a fractionating valve, which are also housed in the assistant. This compact and powerful system is controlled by our extremely user-friendly software PurityChrom®.

The low-pressure gradient module (LPG module) turns the isocratic system into a gradient system. It is possible to operate in a ternary as well as a binary mode. In the binary mode, the sample can also be injected via one channel of the LPG module.
Thereby the system pump can be used simultaneously as a sample pump and very large sample volumes can be applied
without any problems.

Injection with VariLoop

The KNAUER VariLoop is the optimal solution if medium to large sample sizes are to be applied to the column. The VariLoop can be filled completely or partially, as well as completely or partially emptied. This allows very flexible and automated work and the easy exchange between different sample volumes. A constant and reproducible result is achieved for each sample volume. In contrast to all other methods for the injection of large sample volumes, the KNAUER VariLoop allows a nearly lossless sample application.
